A High-Pressure Flux Method to Synthesize High-Purity Oxyhydrides

Adding a flux during the synthesis of oxyhydrides is a promising strategy to obtain a pure, homogenous product, reveal scientists from Tokyo Tech. An SrCl2 flux promoted the melting of a part of reactants and facilitated their diffusion of reactants, which proved to be the key to producing highly pure SrVO2.4H0.6 or Sr3V2O6.2H0.8 perovskite oxyhydrides in high-pressure and high-temperature reactions. These compounds have potential as catalysts and as electrode materials for lithium-ion batteries.
